So has anyone found a cold air intake for the 4th Gen LS460? If so please to tell. I saw on ID injen has universal fit. I’ve searched a lot on google and on a few websites like autozone and priory’s are they only have the square/rectangle air filters and those say they boost airflow, HP, and performance I guess.

oh okay so then I should just stick with getting the air filters since for some reason the air filters say they increase HP performance and such.
Those air filters do nothing but increase intake noise giving the illusion of more power. Any hp increase will be too little to feel.
What you will get it increased silicate, (dirt) aluminum and iron (engine) in your oil. I did a Blackstone oil analysis test on my 2UR before, during and after a K&N filter change and threw it in the garbage when I got the results back.

Probably best to go with OEM replacements or equivalent and perhaps save some money, as well as save us from another debate/thread about which air filter to choose.
It would actually be a downgrade, the 460 has the best airbox of any of the UR equipped cars/trucks. The GS 460 is a great example of how a more normal setup doesn't produce as much power as the mirrored system in the LS
The ISF/GSF/RCF have to make due with the single box setup due to packaging constraints but the engine itself is superior in those cars.

That's incredible that the single intake yielded such significant decreases in horsepower and torque, 10% (38hp) & 7.6% (28lb-ft). Are there any other differences between the two platforms, like maybe exhaust systems perhaps?

Yes, the GS460 has to make due with the AWD LS460 manifolds.
The LS is extremely well engineered out of the box and is difficult to improve on
The log tube design in the header (similar to the 4.3) in the AWD model is responsible for decrease in power. Lots of restriction in that set up. The single air box on the maybe not so much.

Intake, headers, exhaust AND tune are different. The GS runs rich from the factory. stick with your factory intake setup.

Yep, that was pretty much the conclusion I figured. I'm happy with my LS and how she runs and don't have any desire really to change the intake. I was only adding to the conversation because there are some that would like a CAI setup (aftermarket type or looking) and/or oil catch can as well. Personally, I don't believe the LS needs either. Been checking in on your GS build thread periodically and am looking forward to when you get the full exhaust system installed. What's the latest info on Sector 7? Did you ever get any sort of baseline dyno numbers for your GS?

Yeah I can't wait for the finished product! The last I heard S7 said they would be doing tunes for a short time, he just sold the S7 FBO GS460, and I think the tuning software was pretty expensive.
The closest I got to a baseline number was with the Invidia midpipe installed. best of those runs was 290whp/290 torque. That midpipe does delete the secondary CATS so i feel it could have gained at max 10whp. I think its safe to say a stock GS460 is around 275/280 whp which would be around 18% drivetrain loss.
